F-2-F-2U HiFi DAC Converter Audiophile Dual AD1865R NOS R2R Decoder FPGA Asynchronous for PC/CD Player, High End Digital to Analog Converter with Coaxial/USB Port for Home Audio (DAC)

Works voltage: AC115V Size: 280mm*220mm*72mm(W*L*H) Package weight: about 3.2kg Input: USB (Amanero USB iis asynchronous digital interface) SPDIF (FPGA only applies to the USB digital input) Output: RCA single ended 1.5vrms DAC CHIP: 2pcs AD1865R Input format support: SPDIF pcm44.1~384khz USB pcm44.1~384kHz DSD format not supported

• ----FPGA Asynchronous Processing Technology DAC.
• ----DAC design adopts NOS structure and current mode output.
• ----Dual AD1865R NOS R2R Decoder with Coaxial/USB Port for home audio device. Coaxial port can be connected to CD player and digital audio interface, USB port can be used to connect to PC (not laptop and mobile phone)
• ----AD1865R uses current type pin output, abandoning bulky voltage output mode and adopting dual parallel output mode to increase output power, which greatly improves overall performance and listening experience. Therefore, this method should be wise as an R2R decoding chip.
• ----The simulation amplification uses JRC5532D+JRC5534D, and after several months of parameter tuning, this combination was finally decided. The power board voltage regulator is designed for the Ansemy model, and the USB use FPGA to receive asynchronous clock processing. The sound background is clean, and the details are clearly improved.
